They're baaaaack. Season Four of The Real Housewives of New Jersey premiered on Bravo on Sunday night, and Theresa Giudice is making a new arch-nemesis in the form of fellow housewife Caroline Manzo.

"She's not going to take any responsibility," Manzo said, reports People, about her ongoing feud with Giudice, which was fueled by the cookbook Giudice recently put out, Skinny Italian, which took an unflattering view of Manzo and insulted her son Chris's idea for a stripper-run car wash.

"She's going to make up excuses, and quite frankly I'm not in the mood," Manzo continued. "I don't want to talk about it. I'm glad I could help you sell cookbooks — what do you want me to say? Little thing called loyalty is clearly lacking."

Manzo feels she is entitled to loyalty from Giudice for helping her launch her cookbook. "Caroline was very hurt because she's really supported Teresa and she's been there for her through everything, Jacqueline Laurita said on the episode.

Even Giudice's brother, Joe Gorga, had some harsh words for his sister. "I believe that she's living a rough life with her husband, she's unhappy and misery loves company," Gorga said.
